Problems solved by technology
[0005] However, the conventional color mapping technology can only adjust the overall color of the original picture through the color of a reference image, that is, the color of the picture can only be modified in the two-dimensional space where the screen is located, and cannot be modified in the virtual scene. Modify color or perform color mapping within a certain three-dimensional area in space
For example, in the case of the need to reflect the mysterious atmosphere in the distant view of the woods, and this atmosphere needs to be expressed by adjusting the color tone of a certain area in the frame, only relying on traditional color mapping technology will not be able to achieve this three-dimensional area. atmosphere adjustment

Embodiment Construction
[0017] The subject matter of the invention will now be discussed with reference to several exemplary embodiments. It should be understood that these embodiments are discussed only to enable those of ordinary skill in the art to better understand and thus implement the content of the present invention, and do not imply any limitation to the scope of the present invention.
[0018] As used herein, the term "comprising" and variations thereof are to be read as open-ended terms meaning "including but not limited to". The term "based on" is to be read as "based at least in part on". The terms "one embodiment" and "an embodiment" are to be read as "at least one embodiment." The term "another embodiment" is to be read as "at least one other embodiment". The term "coordinate" is to be interpreted as corresponding to the position of an object in space (eg, two-dimensional space or three-dimensional space), so the term "coordinate" has the same meaning as the term "position".

The invention discloses a method and system for realizing spherical color mapping. The embodiment of the present invention combines the attenuation characteristics of the light source and the concept of color mapping, and realizes a spherical color mapping technology whose lighting effect is similar to that of a point light source, so that the scene maker can control certain objects in the virtual space when adding post-effects. The spherical area is color adjusted to produce the light attenuation effect of a point light source.
Description
technical field [0001] The present invention relates to computer graphics technology, in particular to a method and system for combining light source characteristics and color mapping characteristics. Background technique [0002] In scenes such as games or animations, some point lights are usually set. A point light source refers to a light source at a certain position in the scene, which will emit light in all directions, and the light intensity will gradually decay with distance. When the computer renders the scene, the lighting calculation of the point light source is a relatively time-consuming calculation. [0003] Usually, after adding post-effects such as fog effects when making a scene, the lighting effect of the rendered point light source will be changed or not what the producer expected, so that the scene producer has to readjust the settings in the scene The parameters of the point light source, and the change of these parameters will in turn affect the perfor...
